Numerous researchers studied the morphology of the testicular descent, including the possible function of the gubernaculum. However, a clear illustration of this process is still missing. The aim of this paper was to illustrate the embryology of the testicular descent in the rat by scanning electron microscopy. In a first phase of the intra-abdominal testicular descent, the testis moves actively from the lower pole of the kidney towards the bladder neck. In a second inguinal phase the testis enters groin and moves in the developing processus vaginalis peritonei caused by the disappearance of the bulb of the gubernaculums testis.
许多研究人员研究了睾丸下降的形态,包括睾丸引带可能的功能。然而,这一过程仍缺乏清晰的阐述。本文的目的是通过扫描电子显微镜展示大鼠睾丸下降的胚胎学过程。在腹腔内睾丸下降的第一阶段,睾丸从肾下极主动移向膀胱颈。在第二个腹股沟阶段,睾丸进入腹股沟,并在睾丸引带球消失导致的腹膜鞘突发育过程中移动。
